EMBROIDERY-HOOP.

Specification of Letters Patent.

Patented Oct. 23, 1917.

Application filed September 12, 1916. serial No. 119,958.

To all whom it may concern: Be it known that I, GEORGE A. Moonn, a

citizen of the United States, and a resident the ends of the hoop aboutthe embroidery frame and the work between, in order to hold the lattersnugly in place.

In a previous patent granted to me, No. 1,118,213, I set forth a devicefor the purpose comprising a cup-shaped thimble hav-' mg a threadedopening in its bottom into which is screwed one of the hoop-members,while the other hoop-member had a head about which the edges of thecup-shaped thimble were loosely forced to hold it against withdrawal.Notwithstanding the eXcellencies of the same, I have found it inpractice to be somewhat expensive to manufacture.

To reduce the expense to the minimum, I form an internal flange in oneend of a tubular thimble, and thread the remainder of its interior. Theheaded hoop-member is then inserted small end first from the threadedend of the thimble, and given a bend to prevent its accidental fallingout; and the other hoop-member which has had its end swaged to a largerdiameter and threaded to fit the internal threads of the thimble, hassuch threaded end screwed into the thimble.

In the drawings forming part of this specification, Figure 1 is a viewon a reduced scale of an embroidery hoop provided with my improvedtightening device. Fig. 2 is a longitudinal section on a larger scale ofthe thimble. Fig. 3 is a similar sectional view but showing thehoop-members engaged therewith. Fig. 4 is a side view of the headedhoop-member. Fig. 5 is a side view of the hoop-member having an enlargedthreaded head. Fig. 6 is an end view of the thimble.

As shown in Fig. 2, the thimble 1 is a substantially thin walled tubehaving an internal flange 2 atone end to form a comparatively small hole3, and having the interior formed with screw threads 4. While Gopies ofthis patent may. be obtained for five cents each, by addressing the GoWasgtonmw it is less expensive, so far as material is concerned, to formthe thimble from tubing, with the flange 2 spun inward therefrom, I

find that it is more economical in labor to make the same from eithersolid rod metal,preferably brass, or from heavy tubing whose bore isabout equal to the size of the hole 3. This rod, or heavy tubing,

being fed to a turret lathe or automatic screw machine, its interior isfirst drilled and reamed out to the form illustrated, the interiortapped, and then the thimble section separated from the remainder of therod or tubing by the cut-off tool.

The exterior of the thimble should, however, be knurled as shown in Fig.1 before it is thus out 0d. 1 r p A slight head 5 is formed on the hoopmember 6, preferably by upsetting the metal thereat, and suitable rivetholes made through it for the reception of rivets 7 by which it is to befastened to the hoop 9, after which it is inserted in the thimble andthrough the hole 3 until its head 5 is stopped by the flange or shoulder2. It is then given the double bend 10 shown in Figs. 1 and 3, andattached to said hoop by the rivets.

The hoop-member 11 has upset thereon a large head 12 of a diameter tohave its threads 13 properly screw within the threads 4: of the.thimble,and it is also given a double bend 15 like that already shown at 10, andsuitably fastened to the other end of the loop 9, as by rivets 16. Byrotatingv the thimble, the hoop is tightened or loosened as desired.

What I claim is:

An embroidery hoop comprising a hoopmember, a wire attached to thehoop-member at one end and having its other end enlarged and threaded, awire having one end formed with a head larger than the diameter of thewire but smaller than the threaded enlargement of the first-named wire,the other end of the second-named wire being attached to an end of thehoop-member opposite to that to which the first-named wire is attached,and a section of tubing having one end internally flanged and the premainder of its interior screw threaded to cooperate with said threadedenlargement.

In testimony that I claim the foregoing invention, I have hereunto setmy hand this 12th day of September, 1916.-

GEORGE A. MOORE.
